Terminology
Base Resistance - The resistance value
of a thermistor at a specified temperature with negligible
electrical power to avoid self heating.Usually base resistance
will be defined at 25 °C.
BETA - BETA(25C/85°C)
is a "material constant" that defines the Resis.-Temperature
curve slope. It is calculated using the following equation:
[(lnR25-lnR85)/(1/T25-1/T85) Note: Absolute Temperature in
degrees Kelvin(°K)
must be used(°C
+ 273.15) in the calculation.
